Title: Manufacture of high toughness steel wire
Inventor: SHIMIZU KENICHI
IPC: C21D9/52
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a high toughness steel wire, in which the micro-segregation formed in a casting stage is reduced and a steel wire improved in twisting characteristic is obtained. SOLUTION: The method of manufacturing a high carbon steel wire includes a step of hot-rolling a steel wire bar to wire rod and a step of patenting this wire rod. In the course between the hot rolling step and the patenting step, soaking is performed in inert gas at 1150-1300 deg.C for 5-120 min. The micro- segregation of a solute can be sharply decreased by the application of soaking to the wire rod after rolling, and pearlitic transformation at patenting can be uniformized to a greater extent. As a result, twisting characteristic after wire drawing can be greatly improved.

Title: Production of color filter
Inventor: MORI YASUKI
IPC: G02B5/20
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a color filter in which a photosensitive film is excellent in following up ability and workability, with which multicolored fine patterns having uniform thickness and high precision are formed on a substrate and which is excellent in heat resistance. SOLUTION: The multicolored patterns are formed on the transparent substrate by repeating processes including (1) a sticking process in which the photosensitive film composed of a base film and a colored photosensitive resin layer is stuck so that the colored photosensitive resin layer is faced to the substrate, (2) an exposing process in which the photosensitive film is exposed in pattern shapes and (3) a developing process of the film.  In the method for manufacturing the color filter in which the multicolored patterns are formed on the transparent substrate, a process in which the photosensitive film is stuck by forming spaces between pixels is performed so that the colored photosensitive resin layer at an after second coloring faces the substrate and then a transferring process in which the colored photosensitive resin layer at and after second colorings is transferred from the base film to the spaces between the pixels by heating is performed to form the multicolored patterns. Thus, the width of the pixel is made <=50μm and a repeating cycle among pixels of the same color is made <=150μm.

Title: Higher-harmonic compensation apparatus
Inventor: OGAKI YUJI
IPC: H02H3/52
Filed: 1993-05-07
Abstract: PURPOSE:To make it possible to prevent the fault and stop caused by a DC overvoltage or DC short voltage even if the DC voltage of an inverter circuit is suddenly changed by providing a comparator, which detects the DC voltage of the inverter circuit, a limiter circuit and a timer circuit. CONSTITUTION:A comparator 31 always detects the DC voltage of an inverter circuit. When the detected DC voltage exceeds the specified voltage level, the signal is outputted into a timer circuit 32. During the period, wherein the DC voltage exceeds the specified level, and after returning from the specified voltage level, the timer circuit 32 operates a limiter circuit 33 for a specified time. The limiter circuit 33 inserts the effective power axis, which is obtained by the coordinate conversion and operation based on a fault load current, between a filter circuit 26 and a reverse conversion circuit based on the command from the timer circuit 32 and narrows the higher-harmonic current command of the effective power (P axis). Thus, the fault and service interruption caused by the DC overvoltage or the DC short voltage can be prevented even if the DC voltage of the inverter circuit is suddenly changed.
